AI-Thinker has a dev board which contains a relay, buzzer, a temperature/humidity sensor and a number of different colour LEDs, the intention apparently being to provide a simple device to start playing with IoT.

However, the ‘brains’ of the board is not the ESP-8266 on the board but is in fact an STC15L2K32S2 microcontroller which unfortunately is what the relay, buzzer, sensor and LEDs are connected to.

However, you can still make use of the ESP-8266 by isolating it from the STC chip.

This expansion shield for fire beetle is just right for makers who love using terminal blocks for wiring up their projects!

Compared with the previous FireBeetle shields, it comes with additional 7-24V external voltage input and GDI port and adopts terminal blocks to secure wires so as to make connections more stable and reliable. Each terminal block (except GND) has an LED for status indication. Since these LEDs also consume power, which leads to higher power consumption, an LED switch is designed on the board to allow users to turn off the LED when not required.

The NanoPi R2S (as “R2S”) is a FriendlyElec mini-router with edge-computing and dual Gbps Ethernet ports. It is highly compact such that it could be perfectly enclosed in a custom metal case of 60 x 61 x 27 .5 mm.

The NanoPi R2S uses Rockchip’s quad-core A53 RK3328 SoC with powerful performance. Its default frequency is 1.2GHz . The NanoPi R2S has 1GS (or optional 2GS) RAM,dual Gbps Ethernet ports. It uses RK805 PMU chip and supports dynamic frequency scaling. It has one USS 2.0 port that can interface with 4G modules, USS HD cameras,USS WiFi modules etc.

The NanoPi R2S suppors TF card booting. It works with FriendlyWrt, UbuntuCore, Armbian etc and has good support from various communities among which OpenWrt supports it in the mainline versions. These systems are based on Linux-5.4(LTS). The NanoPi R2S is powered through USS Type-C. It is a good choice for applications that need to be deployed in compact space and need strong networking performance.

Features:

1. Light weight
2. Easy to use
3. Plug and play device
4. Low power consumption
5. Compact design

Packages Includes:

1 x NanoPi R2S

Designed by Raspberry Pi, RP2040 features a dual-core ARM Cortex-M0+ processor with up to 133MHz clock and 264KB internal RAM, and supports USB 1.1 devices, which allows users to focus on function implementation instead of spending too much time and effort on improving codes.

DFRobot Beetle RP2040 is a development board built around the RP2040 chip. It has a compact size of 27mm×20mm, which is easy to be embedded into small devices or projects.

The board adopts a beginner-friendly large pad design, effectively reducing the difficulty of soldering. And it provides 8 carefully-selected GPIO ports that can serve as I2C, UART, SPI, digital port, analog port, etc., more convenient and flexible for users to develop various applications.

CM4 Media is a multimedia computer designed based on Raspberry Pi Compute Module 4. It provides 2 channels of USB 3.0, 1 channel of USB2.0, 1 channel of Gigabit Ethernet interface, 2 channels of HDMI interface supporting 4K video output, an 8-megapixel camera, and 2 channels of stereo speakers. You can play Audio and video without additional accessories.
You only need to press the power button to start or shut down the computer like operating a Windows computer. The operating system can be installed on the SSD hard disk and it boots faster than from an SD card. The large-capacity SSD hard disk can store various video data. The access speed of the SSD hard disk is up to 300MB/S.
CM4 Media installed Raspberry Pi-certified external WiFi and Bluetooth dual-band antennas to provide better wireless signals.
You can load different application software to turn the CM4 Media multimedia computer into a network set-top box, network storage server, wireless access point, and other different devices.
CM4 Media’s case is made of CNC-cut aluminum alloy, very beautiful. The case provides excellent heat dissipation performance for the CPU, PMU, and wireless module, which improves the system’s reliability. You can choose black, silver and pink colors.

Package Includes:

1 x EDATec CM4 Media Baseboard CM4104000 4GB DDR,120G SSD WiFi/Bluetooth Antenna Silver Color CNC Aluminum Case 8MP Camera
